All in one wood based mushroom grow bag substrate to simplify the mushroom cultivation process. This bag will work with all gourmet wood loving mushroom strains. Carefully constructed your all in one grow bag has different layers of substrates so there is no need to transfer substrates to different bags or trays thus reducing the chance of contamination. The all in one grow bag is hard wood based for all wood loving mushroom species. Fully hydrated and sterilized with a five micron filter patch and self healing injection port. Simply inoculate the rye berry layer of the substrate with 2-5 cc of your favorite gourmet mushroom spore solution. After inoculation allow your all in one bag to colonize in room temps for 4-6 weeks until your first flush of mushrooms. Mixing the bag once after 50% colonization is optional and can increase colonization times. These bags hold three pounds (about four quarts of substrate) which is much more substrate than the competition offers. Use the contact us link for a quote on bulk orders.
